damccorm opened a new issue, #19925: URL: https://github.com/apache/beam/issues/19925
Using `Void` as key type for grouping operations fails due to the fact that its only value is `null` and SamzaRunner does not accept using `null` values as keys. Other runners seem to work fine with that. Imported from Jira [BEAM-8529](https://issues.apache.org/jira/browse/BEAM-8529). Original Jira may contain additional context.
